Question

the earth diameter is 7915.5 mi. If Demarcus wants to ride his spaceship around half the earth, what distance will he travel?

Answer 1

Assuming you mean it in terms of length rather than total area travelled, he will travel 3,957.75 miles.

Explanation:

Diameter = 7,915.5

Half of Diameter = Half of the Earth

(7,915.5)/(2) = 3,957.75
